Callinex Announces Acquisition to Expand its Headway Project in the Bathurst Mining District

Highlights:

Executed a purchase agreement to acquire the Headway North claim, which hosts the Pabineau Deposit, that significantly expands the Company’s Headway Project;

The Headway Project shares a property boundary and similar geology with Glencore’s Brunswick No 12 mine, previously the world’s largest underground zinc mine; and

Exploration has identified three high-priority drill targets and several untested near-surface electromagnetic anomalies.

Vancouver, British Columbia – February 28, 2019 – Callinex Mines Inc. (the “Company” or “Callinex”) (TSXV: CNX) (OTC: CLLXF) is pleased to announce that it has executed a purchase agreement to acquire the Headway North claim, which hosts the Pabineau Deposit, that significantly expands the Company’s Headway Project (the “Project”) located in the Bathurst Mining District of New Brunswick (See Figures 1, 2 and 3). The Headway Project shares a property boundary and similar geology with Glencore’s Brunswick No 12 mine, previously the world’s largest underground zinc mine, where production totalled 137 million tons grading 8.74% Zn, 3.44% Pb, 0.37% Cu, and 102 g/t Ag from 1964 to 2013.

Importantly, this acquisition further solidifies a land package that covers approximately 4 km of strike length along the prolific Brunswick Horizon and encircled by mineral rights held by Glencore and Osisko Mining. Previous exploration has identified three high-priority drill targets and several untested near-surface electromagnetic anomalies.

The Headway Project represents a compelling exploration opportunity with untested targets in the shadow of the world-class Brunswick No 12 Mine and located within potential trucking distance to the Company’s 100% owned Superjack and Nash Creek projects.

The Headway North claim also includes $36,000 in existing work credits, from work previously completed by Nexa Resources S.A., which will allow for the claims to remain in good standing until late-2024 without any additional exploration requirements.

The Company will issue the vendor 120,000 shares, representing an implied transaction value of $12,000, and a 1.0% NSR royalty, of which half can be re-purchased for $500,000, subject to TSX Venture Exchange approval. Additionally, the Company has completed its previously announced acquisition of the Headway Project (See News Release dated November 14, 2018).

J.J. O’Donnell, P.Geo, a qualified person under National Instrument 43-101 and a Consulting Geologist for Callinex, has reviewed and approved the technical information in this news release.

Mineral Resources are categorized according to CIM Definition Standards; it cannot be assumed that all or any part of Inferred Mineral Resources will be upgraded to Indicated or Measured as a result of continued exploration.

The Nash Creek Mineral Resource Estimate includes the Hickey Zone and Hayes Zone.

The Superjack Mineral Resource Estimates includes the Nepisiguit A (the “A Zone”) and Nepisiguit C Zones (the “C Zone”).

Zinc equivalent Mineral Resources for the Superjack Project were calculated using metal prices of $1.12/lb for zinc, $1.06/lb for lead, $2.97/lb for copper and $20.38/oz for silver. Metal recoveries have been assumed to be 100% for zinc, 72% for lead, 86% for copper and 70% for silver. A cut-off grade of 1.5% Zn Eq. was utilized in the Mineral Resource Estimate.

Numbers may not add due to rounding.
